STORAGE BATTERY.

SPECIFICATION forming part of Letters Patent No. 762,847, dated J' une 14, 1904.

Application filed September 4, 1903. Serial No. 171,954. (No model.)

Be it known that 1, MAX SCHNEIDER, manufacturer, of Bienertstrasse No. 17, Dresden- Plauen, Germany, have invented a new and useful Storage Battery, of which the following is a specification. v

This invention relates to improvements in storage batteries of that kind in which the positive-pole electrode is formed of a plurality of downwardly-convcrging ribbed'lead cones put one above the other and fastened in the center to a lead core by melting and the negative-pole electrode is formed of a hollow metal cylinder encompassing the positive electrode. The improvements are destined to render the storage battery more eective; and the objects of my improvements are, first, to vertically and radially divide the lead cones and most part of the lead core of the positive-pole electrode into halves or several parts; second, to provide the negative-pole electrode either with one vertical internal partition-wall or with several vertical internal partition-walls crossing cach other for engaging in the spaces between the parts of the positive-pole electrode, and, third, to hang the positive-pole electrode on the upper edges of the partitionwalls of the negative-pole electrode. I attain these objects bythe storage batteries illustrated in the accompanying drawings, in

` which- Figure 1 is a vertical section through a storage battery on the line AB in Eig. 2, the positive-pole electrode being divided into halves. Eig. 2 is a horizontal section through the same on thebroken line C D in Fig. l.

Similar letters of reference referto similar parts throughout both views.

The storage battery comprises a containing vessel f and a cover g., of insulating material, and the two electrodes. The positive-pole electrode of a known construction consists of aplurality of downwardly-converging lead cones a, provided each on the upper surface with a plurality of radial ribs and a plurality of concentric ribs crossing each other, so as to form a plurality of recesses for receiving the active material. The lead cones L are put one above the other and fastened to a tubelike lead core I) by lmelting. several disks a and the core b are entirely divided intoH halves, so that a vertical central space /L is left between them. -The two parts of the positive-pole electrode are preferably shown at Figs. 1 and 2. The fork c is provided with a binding-post @,projecting th rough an opening of the cover g. The negative-pole electrode (l, made of metal or active material ,I tically at d and provided with a vertical central partition-wall d', extending into the slit t', as shown. The negative-pole electrode is placed in the' containing vessel f and there secured 'of any known kind-for example, a fibrous cellulose sheet chemically treated with a neutral salt or the like-is introduced between the containing vessel fand the negative-pole elecknown kind is made to line the internal walls of the negative-pole electrode. Afterward the positive-pole electrode is so introduced that its fork c rests on the upper edge of the partiof the negative-pole electrode d may be omitted. A

The storage battery described so far can be varied in many respects without deviating from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In a storage battery, the combination with a containing vessel, of a cover, a posidownwardly-converging lead Agrid-cones put one above the other and fastened by melting to a central lead core, said lead grid-cones and most part of said lead core up to a point into halves, a hollow cylinder of active material adapted to form the negative-pole electrode inclosin'g said positive-pole electrode and provided with one vertical partition-wall said positive-pole electrode, and means forin- Prcferably the fastened by melting to a lead fork c, as is in a known manner, is in this case slitted verin a suitable manner. An insulating-body 7c 65 trode, and equally an insulating-bodyl of any tion-wall 0l. Where so preferred, the slit e' 75 tive-pole electrode formed of a plurality of near the upper end being vertically dividedv y engaging in the space between the halves of said positive-pole electrode and provided with a plurality of vertical radial partition-Walls engaging in the spaces between the parts of said positive-pole electrode, and means for insulating saidA negative-pole electrode fromsaid containing vessel and from said positivepole electrode.

In testimony whereof I have signed my name to thisspecilieation in the presence of two subscribing Witnesses.
